New to the forum, so please bear with me.
Have a 2002 7.3 super crew. I had an oil leak that turned out to be a bad "O" ring on a high pressure oil return line. Among the black spot on the driveway I noticed I had oil pooling on top of the intake manifold. Got the "O" ring leak fixed, but I still have a leak somewhere up high (still oil on top of manifold). Not a lot of oil is dripping down now, but I don't like it regardless.

Any thoughts on where it might be comming from?

 

what i have read from others on here, is to clean your engine compartment then finding the a leak will be more noticible.
I used simple green and a garden hose, several doses cleaned everything up pretty good, good enough to find an oil leak.
check you boots on your inter cooler lines to make sure they are tight.

dont forget to put your alternator in a plastic bag.

 

I had a problem with an O-ring from my HP crossover line. I didn't pay attention to the instructions and overtightened the fitting. It could still be from your o-ring you replaced if you overtightened it. When mine was sitting, there was just barely a hint of oil under the side that was leaking, but I guess there is a lot of pressure and I had a lot of oil running to the back of the engine and puddling on the ground.

Turbo pedestal O-rings have been known to leak as well.

Good luck.

 

I just had the same problem as you, after I replaced all three o-rings and pulled my truck out to the driveway it continued to drip for a day or so. What I did was take it to the car wash place and high pressure wash the engine, I also did this when tryying to find the oil leak. First I washed it with the engine degreaser/tire cleaner then I high pressure rinsed it. Since then I have noticed no more oil on top of the engine and no more nasty little oil stains in the driveway.

Just make sure not to put the gun right up against anything in the engine compartment, i.e. use common sense, and everything will be fine. I have also heard of guys using simple green and rinsing with a garden hose, either way should work just fine.

Hopefully this will solve your problem, or help you find the new issue.

 

The importance of keeping the valley clean is the drips that start showing up on the driveway could actually be caused by a fuel leak. If the drain valve o-rings or a fuel rail fitting starts to leak, it will mix with the oil, grease and crud on the top and back of the engine and ends up on the ground appearing to be an oil leak.
